(15) Install input clutch assembly to the Input
Clutch Pressure Fixture±Tool 8391 (Fig. 261).
(16) Set up dial indicator on the UD clutch pack as
shown in (Fig. 262).(17) Using moderate pressure, press down and
hold (near indicator) the UD clutch pack with screw-
driver or suitable tool and zero dial indicator (Fig.
263). When releasing pressure on clutch pack, indica-
tor reading should advance 0.005±0.010.
CAUTION: Do not apply more than 30 psi (206 kPa)
to the underdrive clutch pack.
(18) Apply 30 psi (206 kPa) to the underdrive hose
on Tool 8391 and measure UD clutch clearance. Mea-
sure and record UD clutch pack measurement in four
(4) places, 90É apart.
(19) Take average of four measurements and com-
pare with UD clutch pack clearance specification.
Underdrive clutch pack clearance must be 0.94-
1.50 mm (0.037-0.059 in.).
(20) If necessary, select the proper reaction plate
to achieve specifications:

OIL PUMP
DESCRIPTION
The oil pump is located in the pump housing inside
the bell housing of the transaxle case (Fig. 283). The
oil pump consists of an inner and outer gear, a hous-
ing, and a cover that also serves as the reaction shaft
support.
OPERATION
As the torque converter rotates, the converter hub
rotates the inner and outer gears. As the gears
rotate, the clearance between the gear teeth
increases in the crescent area, and creates a suction
at the inlet side of the pump. This suction draws
fluid through the pump inlet from the oil pan. As the
clearance between the gear teeth in the crescent area
decreases, it forces pressurized fluid into the pump
outlet and to the valve body.
DISASSEMBLY
When disassembling the transaxle it is necessary
to inspect the oil pump for wear and damage.
(1) Remove the reaction shaft support bolts.
(2) Remove reaction shaft support from pump
housing (Fig. 284).
(3) Remove the pump gears (Fig. 285) and check
for wear and damage on pump housing and gears.
(4) Re-install the gears and check clearances.
(5) Measure the clearance between the outer gear
and the pump pocket (Fig. 286). Clearance should be
0.089±0.202 mm (0.0035-0.0079 in.).
(6) Measure clearance between outer gear and
crescent. Clearance should be 0.060-0.298 mm
(0.0023-0.0117 in.).
(7) Measure clearance between inner gear and
crescent. Clearance should be 0.093-0.385 mm
(0.0036-0.0151 in.).
(8) Position an appropriate piece of Plastigage
across both pump gears.
